摘要:
A survey of normal stress measurements for polyisobutylene fluids is made. The first normal stress(N1)data are correlated withN1c2/τ2as a very weak function of concentration (c), molecular weight (M), and shear stress (τ). We also find the second normal stress as about −0.15 ofN1.The limitations of this empirical correlation are discussed.
